"Richard Dawson's project that debuted on Blackest Rainbow earlier this year, which was followed by CDRs on Bells Hill, Low Point and Dead Pilot, and another release on Blackest Rainbow, a split cassette with fellow UK droner Gareth Hardwick. The Invisible Castle is far more intense, and in some ways heavier than the previous releases on BR, but retains Dawson's own dark take on the world of psychedelic drone music, and this is a proper drone release, clocking in an hour for the full piece. Limited to 1000 copies in pro-printed wallets."
